Men, bring your kids and grandkids for a pre-game cookout at the Hamilton Park pavilion and then a night of baseball with the Frederick Keys. The pre-game activities begin at 3:30 p.m., followed by hot dogs and burgers at 4 p.m. We will depart about 4:45 p.m. for the 6 p.m. game in Frederick MD, where the Keys will take on the Potomac Nationals.
